"Zero-field and Larmor spinor precessions in a neutron polarimeter experiment";
Physics Letters A, 372 (2008), S. 3153 - 3156.

We present a neutron polarimetric experiment where two kinds of spinor precessions are observed: one is induced by different total energy of neutrons (zero-field precession) and the other is induced by a stationary guide field (Larmor precession). A characteristic of the former is the dependence of the energy-difference, which is in practice tuned by the frequency of the interacting oscillating magnetic field ω_R. In contrast the letter completely depends on the strength of the guide field, namely Larmor frequency ω_L. Our neutron-polarimetric experiment exhibits individual tuning as well as specific properties of each spinor precession, which assures the use of both spin precessions for multi-entangled spinor manipulation.
